8 months ago For whoever is going to work on this bug, the issue also affects strings, not only string literals:
arr.forEach((_, index) => {
return <div key={"test" + index} />

Expected result
Using an array index in a template literal key should cause an error as the ESLint rule "react/no-array-index-key": https://github.com/jsx-eslint/eslint-plugin-react/blob/master/docs/rules/no-array-index-key.md
Throw a lint-error on usage array-index as key with a template literal.
